The Administrative Office of Pennsylvania Courts said in a statement that Justice J. Michael Eakin will now oversee the court system of the state's largest city. The statement says Eakin will "lead continued reform efforts" begun by Castille.

In a statement, Eakin says the chief justice's responsibilities are "immense" and that overseeing the city's court reform requires significant work. He says the court will continue pushing forward Castille's reforms.

Castille, a former Philadelphia district attorney, says in a statement that he is proud of what he has accomplished as the liaison justice to the city's courts since 2007.
